RAM Air Flow | Engineers with Markers

In this video, Tanner McFarland, an engineer at Advanced Cooling Technologies, provides an overview of RAM Air Heat Exchangers and how they work to cool high-speed vehicles, particularly aircraft. He explains the key components, including the air inlet, diffuser, and heat exchanger, which utilize airflow around the vehicle to transfer heat. By slowing down the incoming air to build static pressure, the system induces a flow that helps reject heat efficiently. Tanner also highlights the importance of heat exchanging geometry design and the influence of flight altitude on air properties such as temperature and density. The video covers various cooling applications, including the cooling of electronic components and cabin systems. This brief but informative introduction is ideal for those interested in the design and functionality of RAM Air Heat Exchangers in aircraft and other vehicles.
